AUTOMOBILE TRAFFIC-SIGNAL.

Specification of Letters remit.

Patented Oct. 21,1919.

Application filed April 30, 1018. Serial No. 281,703.

i To all whom it may concern:

Be it known that I, DANIEL G. Gist-nu, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented a certain new and useful Automobile Traflic- Signal, of which the following is a specification.

The invention relates to a trailic signal adapted to be carried by an automobile.

An object of the invention is to provide a signal on an automobile which indicates to the driver of another vehicle, meetin the automobile at a street intersection, w ich vehicle has the right of way. Many accidents are caused at street intersections due of drivers with the rules of the road, an an object of this invention is to provide a signal on an a11tomobile which W111 cause drivers to obey the rules of the road without being familiar with them.

The rules rovide that at street intersections, the ve icle approaching the crossing from the right has the right of'way, that is, if the driver of an automobile in appreaching a street intersection observes another automobile approaching theintersee tion from the left on the cross street, the driver of the first automobile has the right of way, Whereas if the vehicle on the cross street was approaching from the right of the driver of the first automobile, the driver of the second automobile has the right of way.

The device of my invention is disclosed in the accompanying drawings in which Figure 1 is aside elevation of the device secured to the filling neck of the radiator of an automobile.

' Fig. 2 is a cross section taken on the line 2-2 Fig. 1.

The device of my invention consists of a disk 3 or other suitably shaped object, which is provided with means for supporting it upon the automobile,preferably in a conspicuous position in front of the automobile. In the present instance the supporting means consists of a bracket 4 provided with a clamp adapted to engage the radiator neck 5. The disk is supported on the automobile, so that it lies in a vertical in the direction of the ongitudinal axis of the automobile, so that when the automobile is observed from the right, the face 6 of the disk is seen and w on observed from the left, the face 7 of the disk is seen. The face 6 of the disk is painted a color such as green, which is universally recognized as indicating a clear track and go ahead, and the face 7 of the disk is painted red, a color which is universally recognized as indicating danger and stop.

Arranged in the disk, preferably at the center, is a cylindrical housing 8, disposed perpendicularly to the disk, and within the lane extending ousing is an electric lamp 9 which is ref-- eraibly connected in circuit with the ead lights of the automobile. The end of the housing l which projects from the disk on the rig t side is closed with a green-lens 12 to correspond to the color of the face 6 of the dlsk and the other end of the housing is closed with a red lens 13 to correspond to the color of the face 7 of the disk.

The device serves therefore, either by day or by night, to signal the approaching car atan intersection either to proceed or to stop, depending upon the direction of ap proach of the car and by providin all antemobiles with such devices, the anger of accidents at street intersections would be vastly minimized. 1

I claim:

A traflic signal comprising a flat late, i the opposite facesof the platebeing o different colors, a, housing arranged within the periphery of the plate, a lam in said housing, lenses in the ends of Bel housing corresponding in color to the adjacent 1: cos of the plate, and a bracket secured to aid plate andladapted to be secured tothe neck of the automobile radiator to fixedly hold the plate in front of the radiator in a vertical plane passing longitudinally through the automobile.

In testimony-whereof, I have hereuntoset my hand at San Francisco, California, this 23rd day 'of April, 1918.
